tests/config/test_config_sid: Mark tasks as noqa 503

The latest ansible-lint failes for the tasks that are using
"when: sid_disabled.changed" with the error
"Tasks that run when changed should likely be handlers.". As
these tasks are tests and it would not make sense to use handlers here,
the tasks have been marked as noqa 503.
